Abstract：
OBJECTIVE: To compare the efficacy of dry needling (DN) and cold-spray-stretching treatments using surface electromyography (sEMG) and ultrasound (US) in the treatment of patients with myofascial pain syndrome (MPS) with active trigger point (ATrP) in the upper trapezius muscle.
METHODS: This prospective randomized single-blind study included 60 MPS patients aged 18-65 years who have ATrP in the upper trapezius muscle. Patients were randomized into two treatment groups as DN and cold spray stretching. Both treatment groups received 1 treatment per week and totally 3 sessions. Evaluation parameters were pain level assessed by Numeric Rating Scale and algometer, neck range of motion angles, neck disability index (NDI). The effects of the treatments on ATrP were evaluated by sEMG and US histogram. All parameters were evaluated at the beginning of the treatment and at the end. Algometer and sEMG were performed also before and after the first and third sessions.
RESULTS: There was no significant difference between the two groups regarding demographic data. The mean age of the participants was 39.7 ± 11.6 years. Fifty-one patients were female. Significant improvement in terms of pain level, functionality, sEMG, and US histogram were achieved in both groups (P < .05). When comparing the two groups, algometer scores and the NDI score were statistically higher in the cold-spray-stretching group than in the DN group (P < .008 and P < .028, respectively).
CONCLUSIONS: Both treatment options should be preferred. The efficacy of both treatments was observed via sEMG and US histograms.

摘要：
目的：比较采用表面肌电图（sEMG）和超声（US）的干针（DN）和冷喷雾拉伸治疗在上斜方肌活动触发点（ATrP）的肌筋膜疼痛综合征（MPS）患者中的疗效。
方法：这项前瞻性随机单盲研究包括60名年龄在18-65岁之间且在上斜方肌有ATrP的MPS患者。将患者随机分为DN和冷喷雾拉伸两个治疗组。两个治疗组每周接受1次治疗，共3次。评估参数是通过数字评定量表和algometer评估的疼痛水平，颈部运动角度范围，颈部残疾指数（NDI）。通过sEMG和US直方图评估治疗对ATrP的影响。在治疗开始和结束时评估所有参数。在第一次和第三次会议之前和之后也进行了Algometer和sEMG。
结果：两组人口统计学数据之间没有显着差异。参与者的平均年龄为39.7±11.6岁。51名患者为女性。疼痛程度显著改善，功能，sEMG,两组均取得US直方图(P<0.05)。当比较两组时，冷喷雾拉伸组的algometer评分和NDI评分在统计学上高于DN组(分别为P<.008和P<.028).
结论：两种治疗方案均应优先考虑。通过sEMG和US直方图观察两种处理的功效。
